Statistics is a general field of numeric quantities and what they represent. For example, a statistic may be inferential or descriptive. Inferential statistics are special kinds of statistics that use sampling distributions to make inferences from a sample to a population of interest (hopefully that the sample represents). The inferences are more or less valid based on how well one meets the assumptions of a statistical method/model and how robust a statistical method is with respect to violations of an assumption.
Interviewing is a systematic method of gathering written or oral information through direct questioning of individuals.
Mathematica can be divided into two parts ; viz. Mechanics, and Statistics. Mechanics deals with the movement of a single object in a population. Statistics deals with the movement of the population as a whole. e.g. A single car may move at 30 mph. The total car population may have an average/mean speed of 20 mph.
